Charm++ parallel programming system

[Matthias Diener <mdiener AT illinois.edu>]

Regarding your questions:

1) We only support the multicore, netlrts, and ucx network layers for
the ARM8 architecture, not the MPI layer.
You would build them with "multicore-arm8", "netlrts-linux-arm8", and
"ucx-linux-arm8", respectively. Note that multicore only supports
running on a single cluster node, so netlrts is probably your best
option.

2) netlrts is our own UDP-based communication layer, while the MPI
layer uses an underlying MPI implementation to communicate.
